' This invention relates to air cleaning machines, and particularly to means for removing dirt a'nddu'St pa rt ic1es,jas well as some of themoisture', froin'the air, after purifying or saturating operations.

The primary obj ectf'ofj the invention is to provide meansof simplifiednature for ap- 'plication to air purifyin machines, I by means of which progress of :the'air may be retarded after the p'urifyingand saturating operations, whereby toefl'ectively remove impuritiesand moistureifrom the air prior to its dischargefromig-the machine.

A further object iiof the invention is to provide an apparatus of thefcharacter mentioned, wherein the-'- air is compelled to take tortuous courses through the machine to contact a relatively great number of times with dust and moisture removing surfaces before being delivered from the machine.

A further object is 'to'prov-ide a device of the-character stated involving the use of a plurality of baflle plates, and wherein the afile plates are constructed in sections and provided with means for their ready attachment and cooperation with each other.

With these objects in view, together with others which will appear as the description proceeds, the invention consists in the novel construction, combination and arrangement of parts, all as will be described more fully hereinafter, illustrated in the drawings, and particularly pointed out in the claims.

In the dr'awin s: I Fig. 1 is a horizontal sectional view taken through an air cleaning machine constructed in accordance with the invention,-

Fig. 2 is a front elevation, parts, broken away, of the machine,

Fig. '3 is a side elevation, of and Fig. 4 is a vertical sectional view taken the machine,

substantially upon line 4-4 of Fig. 1.

The device of the present invention. is adaptable to air cleaning apparatus of that type wherein the/air to be pur1fied 1s first su jected to purifying and moistemng op erations; the present apparatus being designed toreceive the air so treated and to condition the same before being. discharged from the machine. a

The apparatus comprises a plurality of plates of vanes represented at 5, arrangedin spaced parallel relation, relativelyclose' togather, and providing between them a series of channels or passages 6 through which the air passes before belng discharged. These plates are arranged vertically within the machine, and are preferably constructed so as to entlrelyfill the chamber of themachine with which it is associated. I

.The baiile plates orvanes are preferably arranged 1n series or sections, A B, C, the said sectlons being-so constructed "able the same to be readily coupled to and operatively associated with other sections".

as to enof the series. The first series, indicated 1 generally at A, comprises the; plates 5 as shown in Fig. 1, of uniform length and breadth, bent or shaped asshown to prov1de tortuous or sinuous passages through the section. The front portions of the said vanes incline from a straight line passing through the machine so thatthe air isinitial- 1y brought into contact with inclined faces of the plates. The platesthen inclinefor a shortdistance so as to provide an obtuse angle with the first mentioned portions to provide walls against which the air must forcibly'engage in its further travel between the plates. The plates are then disposed or inclined in a directionsubstantially parallelv I with the portions 5. This formation and ar rangement of plates produces abutments at 85'.

points 78, around which the air currents pass and are caused to be brought into intimate contact with the angular walls on the opposite sides of the passages next succeeding The air is thus cause v the said abutments.

to be thrown back and forth laterally of the passages, and the contact of the air with the wallsflthereof causes dust particles, dirt and moisture to be de osited upon the angular faces, from which the bottom of the vanes. The rear extremities of the vanes are provided with pockets indicated at 9. These pockets are formed by bending. or shaping the rear ex tremities of the plates laterally and inwardly, whereby the pockets having angular walls are disposed in direct path of the air 'currents passing over the next preceding abutments 8. :The pockets by thus projecting into the air passa es or channels, receive the volume of air an retard the flow of the same so that dirt particles and moisture will be collected and retained upon the walls thereof. e The sections BO are constructed substantially slmilar to each other, except that the it will gravitate to relatively short vanes 10 thereof incline in directions substantially opposite to each other. Each of the vanes 10 is straight throughout its length, and is provided at its rear with a pocket 11 formed by deflecting the edges of the vanes at substantially right angles from the body portions thereof'and-then turning the extremeedges thereof forwardly to provide closures for the outer sides. of the pockets. It will be noted that the vanes 10 of the sections BC are spaced greater distances apart than are the vanes of the section A with their pockets progressively increasing in size proportionate to the channels, and the vanes or plates of sections BC are so arranged that the passages between them are disposed directly rearwardly of the discharge endsof the channels of the next preceding section.

By reason of the particular shapeand arrangement of the plates 5 of the section A, the pockets Qthereof are out of direct longitudinal alignment with any 'ofthe abutments 78. This construction compels the air currents to move into contact with a relatively great area of plate surface before being delivered from'the particular section.

The assemblage of the vanes 10 of the sections 13-0 is such that the pockets thereof are out of direct longitudinal alignment wlth each other as well as withthe pockets of the section A. This arrangement compels the air currents to follow such a sinuous course as to bring thesame into intimate contact with a multiplicity of vane and pocket surfaces before being delivered from the washer. Dirt and dust particles, as well as moisture, coming in contact with such surface collects thereon and gravitates to the lower ends of the vanes, where it may be collected or dis posed of in any suitable manner.

The vanes of the several sections are maintained rigidly in. proper position by bars or plates 12 at the front and rear edges thereof. These plates are provided at their edges with recesses as shown to receive the edges of the adjacent plates, and channel irons such as represented at 13 connect the end vanes of the section with the said plates or bars 12. Similar channel members 14 may extend between the plates 12 intermediate the lateral ends of the section to lend rigidly to the structure.

The sections thus constructed and assembled cause the currents of air entering the channels to take courses substantially 'as outlined by the arrows in Fig. 1 of the drawing. The arrangement of baffle walls is such that the currents .of air follow zig-zag courses through the passages and the volume thereof is thrown directly into the pockets at the rear ends of the vanes. The air currents are thus freed of moisture and dirt particles by reason of their being brought into intimate contact with a relatively great number of surfaces.

By constructing the units or sections in the manner specified it is apparent that any desired number of sections may be used in an air washing machine, as they may be applied or removed .as occasion demands. The sections thus interfit with one another, lend rigidity to each other and stabilize the efitire assembled series.

VVhatI claim, is:

1. In an air cleaning machine, primary vanes arrangedin parallel zig-zag relation and forming continuous tortuous air channels each havingoppositely disposed abutments, pockets at the discharge end of said vanes projecting into said channels and disposed in a line intersecting the final abutment therein, opposite bars for supporting said vanes,'and a supplemental series of oppositely inclined parallel vanes supported at the delivery from the prima vanes by a series of parallel bars mounte upon one of the opposite-bars, said supplemental vanesbeing spaced to receive discharge from more than one of the primary vanes and formed with pockets at their delivery end'projected into the space intermediate the supplemental vanes.

2. In an air cleaning machine, continuous primary vanes forming tortuous air channels having oppositely disposed abutments,

pockets at the discharge end of said vanes projecting into said channels and directed toward the final abutment therein, a supplemental series of oppositely inclined parallel vanes disposed at the delivery from the pri mary vanes and having pockets at their delivery ends projected into the space intermediate the supplemental vanes, recessed securing strips adapted to receive the opposite edges of the primary vanes, brace bars conforming to the vanes for securing said' strips together, and secondary recessed strips for supporting the supplemental vanes relative to the final first mentioned strip.

In testimony whereof I aflix my signature.
